<p>Has major progress been made on -Z build-std in the past year?  That was when I was last looking at the feature.  A cursory search for information was fruitless.  Given the niche use case, asking seemed like the best course of action.  My goal to use std on a closed proprietary AArch64 target.</p>

<p>There is progress, but it is slow (FWIW, I opened a significant PR a few days ago <a href="https://github.com/rust-lang/rust/pull/74033">https://github.com/rust-lang/rust/pull/74033</a>).  I would not rely on it for anything serious.  You can follow the tracking issue at <a href="https://github.com/rust-lang/wg-cargo-std-aware/issues/9">https://github.com/rust-lang/wg-cargo-std-aware/issues/9</a> for major milestones.</p>

<p>I'm curious if there's any plan to migrate <code>rustbuild</code>/<code>bootstrap</code> to use <code>build-std</code>....</p>

<p><span class="user-mention" data-user-id="116458">@Charles Lew</span> No plan, and it is very low priority. More details in <a href="https://github.com/rust-lang/wg-cargo-std-aware/issues/51">https://github.com/rust-lang/wg-cargo-std-aware/issues/51</a></p>
